MailEnable Enterprise Premium before 10.62 Heap Overflow via IMAP X-FB-FETCH

MailEnable Enterprise Premium before 10.62 contains a heap overflow vulnerability in the IMAP X-FB-FETCH command that allows authenticated users to overflow a fixed 0x400-byte heap buffer. Attackers can supply an X-FB-USER address longer than about 1016 bytes, which is formatted without a length check, to crash the IMAP service and cause denial of service.

MailEnable Enterprise Premium < 10.55 Authorization Bypass via WebAdmin

MailEnable Enterprise Premium 10.55 and earlier contains an improper authorization vulnerability in the WebAdmin mobile portal that allows attackers to bypass authentication checks by reusing AuthenticationToken cookies generated for low-privileged users. Attackers can obtain a token from the WebMail login endpoint using the PersistentLogin parameter and replay it against the WebAdmin portal to perform highly privileged administrative actions.

Multiple stack-based buffer overflows in the IMAP module (MEIMAPS.EXE) in MailEnable Professional 1.6 through 1.82 and 2.0 through 2.33, and MailEnable Enterprise 1.1 through 1.30 and 2.0 through 2.33 allow remote authenticated users to cause a denial of service (crash) or possibly execute arbitrary code via a long argument to the (1) EXAMINE or (2) SELECT command.

Stack-based buffer overflow in the IMAP service for MailEnable Professional and Enterprise Edition 2.0 through 2.35, Professional Edition 1.6 through 1.84, and Enterprise Edition 1.1 through 1.41 allows remote attackers to execute arbitrary code via a pre-authentication command followed by a crafted parameter and a long string, as addressed by the ME-10025 hotfix.

The IMAP service for MailEnable Professional and Enterprise Edition 2.0 through 2.34, Professional Edition 1.6 through 1.83, and Enterprise Edition 1.1 through 1.40 allows remote attackers to cause a denial of service (crash) via unspecified vectors that trigger a null pointer dereference, as addressed by the ME-10023 hotfix, and a different issue than CVE-2006-6423. NOTE: some details were obtained from third party information.

Stack-based buffer overflow in the POP service in MailEnable Standard 1.98 and earlier; Professional 1.84, and 2.35 and earlier; and Enterprise 1.41, and 2.35 and earlier before ME-10026 allows remote attackers to execute arbitrary code via a long argument to the PASS command.

Buffer overflow in NTLM authentication in MailEnable Professional 2.0 and Enterprise 2.0 allows remote attackers to execute arbitrary code via "the signature field of NTLM Type 1 messages".

Stack-based buffer overflow in the IMAP service in MailEnable Enterprise and Professional Editions 2.37 and earlier allows remote authenticated users to execute arbitrary code via a long argument to the APPEND command. NOTE: this is probably different than CVE-2006-6423.

Multiple unspecified vulnerabilities in the SMTP service in MailEnable Standard Edition 1.x, Professional Edition 3.x and earlier, and Enterprise Edition 3.x and earlier allow remote attackers to cause a denial of service (crash) via crafted (1) EXPN or (2) VRFY commands.

Multiple buffer overflows in the IMAP service (MEIMAPS.EXE) in MailEnable Professional Edition and Enterprise Edition 3.13 and earlier allow remote authenticated attackers to execute arbitrary code via long arguments to the (1) FETCH, (2) EXAMINE, and (3) UNSUBSCRIBE commands.

The IMAP service (MEIMAPS.exe) in MailEnable Professional Edition and Enterprise Edition 3.13 and earlier allows remote attackers to cause a denial of service (crash) via (1) SEARCH and (2) APPEND commands without required arguments, which triggers a NULL pointer dereference.

Unspecified vulnerability in a cryptographic feature in MailEnable Standard Edition before 1.93, Professional Edition before 1.73, and Enterprise Edition before 1.21 leads to "weakened authentication security" with unknown impact and attack vectors. NOTE: due to lack of details, it is not clear whether this is the same as CVE-2006-1792.

The NTLM authentication in MailEnable Professional 2.0 and Enterprise 2.0 allows remote attackers to (1) execute arbitrary code via unspecified vectors involving crafted base64 encoded NTLM Type 3 messages, or (2) cause a denial of service via crafted base64 encoded NTLM Type 1 messages, which trigger a buffer over-read.

MailEnable Enterprise 1.1 before patch ME-10009 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via several "..." (triple dot) sequences in a UID FETCH command.

Unspecified vulnerability in MailEnable Enterprise Edition before 1.2 allows remote attackers to cause a denial of service (CPU utilization) by viewing "formatted quoted-printable emails" via webmail.

Webmail in MailEnable Professional Edition before 1.73 and Enterprise Edition before 1.21 allows remote attackers to cause a denial of service (CPU consumption) via unspecified vectors involving "incorrectly encoded quoted-printable emails".

MailEnable Professional Edition before 1.53 and Enterprise Edition before 1.02 allows remote attackers to cause a denial of service (crash) via malformed (1) SMTP or (2) IMAP commands.

The SMTP service of MailEnable Standard 1.92 and earlier, Professional 2.0 and earlier, and Enterprise 2.0 and earlier before the MESMTPC hotfix, allows remote attackers to cause a denial of service (application crash) via a HELO command with a null byte in the argument, possibly triggering a length inconsistency or a missing argument.

SMTP service in MailEnable Standard, Professional, and Enterprise before ME-10014 (20060904) allows remote attackers to cause a denial of service via an SPF lookup for a domain with a large number of records, which triggers a null pointer exception.

Unspecified vulnerability in the POP service in MailEnable Standard Edition before 1.94, Professional Edition before 1.74, and Enterprise Edition before 1.22 has unknown attack vectors and impact related to "authentication exploits". NOTE: this is a different set of affected versions, and probably a different vulnerability than CVE-2006-1337.
